5 Claims.

This invention relates to a combined cutter and scraper, .and has for one of its objects the production of means for cutting and scraping flesh and fat free of hide, and simultaneously separating the meat from the hide with the cutting of strips of hog and similar meat into small particles for domestic purposes.

A further object of this invention is the production of a simple and efficient means for firmly holding the scraper-knife in an adjusted tilted position and to facilitate the adjustment of said scraper-knife to a minute degree.

The present invention constitutes an improvement upon the machine as covered in Patent #1365927, dated January 18, 1921.

Other objects and advantages of this invention will appear throughout the following specichine;

Figure 3 is an irregular fragmentary longitudinal section of the machine, certain parts being shown in side elevation;

Figure 4 is a side elevational view of the operating gear mechanism;

Figure 5 is a fragmentary vertical sectional view taken on line 5-5 of Figure 2;

Figure 6 is a side elevational view of the scraper-knife and its operating 'parts, certain parts being shown in section;

Figure '1 is a sectional view taken on line 1--1 of Figure 6;

Figure 8 is a fragmentary side elevational view of the frame showing the slot formed therein to permit of the proper adjustment of the scraperknife.

By referring to the drawings, it will be seen that l designates the frame of the machine which carries a main driving shaft I I. This driving shaft drives a train of gears A for rotating a shaft |2 carrying a series of feeding elements l4 and cutting discs l5 of the conventional type, in the direction of the arrow indicated in Figure 3.

A scraper-knife roll I6 is located directly below theshaft l2 and in alignment therewith, and this scraper-knife roll IE carries a plurality of spaced serrated collars or toothed discs H. An adjustable scraper-knife roll |8 carrying a plurality of spaced serrated toothed discs is mounted in substantial horizontal alignment with the roll IS. The discs H are arranged in staggered relaand I8 are adapted to draw the hide down between the rolls as set forth in the following description. This roll I8 is carried by the upstanding links 20 which links are carried by a transverse journal shaft 2|. A vertical extending adjusting lever 22 is also joumaled upon the shaft 2| and engages at its upper end the roll I8. The

lower endof the lever 22 is pivotally engaged by support 24 and limit the movement of the link 23 in one direction. A coil spring 25 is carried by the link 23 and abuts the support 24 to yieldably urge the lower end of the lever 22 away from the support and the roll l8 toward the roll l3. By adjusting the lock nuts 23a the lever 22 may be rocked upon the shaft 2| to move the roll l8 toward or away from the roll I8, and the coil spring 25 will hold the lever 22 in a yieldable position so that the roll l8 under excess pressure may yieldably swing away from the roll IS. The rolls l6 and H! are driven by the spur gears 8 and 9 respectively which form segments of the train of gears A in a manner similar to the spur gears 2| and 22 mentioned in my Patent Number 1,365,927, referred to above.

A scraper-knife 26 is carried by a transverse bar 21, and this knife or blade 26 is detachably secured to the bar 21 by means of suitable screws 28. This bar 21 is vjournaled at its rear end upon a journal shaft 29 extending transversely By rotating the hand-wheel 33 and consequently v the eccentric shaft 32 it will be seen that the depending arm 30 will be swung forwardly or rearwardly for raising or lowering the knife 26 thereby permitting the knife to be adjusted to a minute degree merely by rotating the operating .handle 33. This knife 26 may belocked in this adjusted position through the medium of a set screw 34 which passes through the frame l0 and engages the bar 21 in the manner shown in Figure '7. The frame is provided with a vertically extending slot 35 through which the set screw tion with respect to the discs l9. The rolls I3 34 extends, and this set screw 34 also passes The bar 21 is shaped on its forward As the hide is severed from the fleshand fat, the latter will be caused to pass to the mincing knives 39 which are carried by an operating shaft l driven through the medium of the gear 4| which meshes with 'a gear 42 of the gear train A.

It should be understood that any suitable or desired means may be employed for driving the cutting discs l5 and feed mechanism, as well as the other moving parts of the machine, without departing from the spirit of the invention.

A suitable cover may be employed for the machine and-the floor and other parts thereof may be suitably slotted to permit proper operation of the parts.

As the hide is scraped from the flesh and fat, it is caught by the teeth I! and IQ of the scraper rolls l6 and I8 respectively, which rolls rotate in opposite directions, the hide is drawn down between the rolls in the same manner as described in Patent No. 1,365,927 above referred to. The serrated toothed discs assist in this drawing supporting said scraper-knife, means for rockably supporting the bar upon said frame, a depending arm carried by the bar and having an aperture formed therein, an eccentric shaft extending through said aperture, a hand-operating means engaging said shaft for rotating the same whereby said bar will be rocked upon its mounting to minutely adjust the bar, and locking means engaging the bar for fixedly holding the bar in a set adjusted position.

3. A machine of the class described comprising a frame, a feeding means, a scraper-knife, a bar process and since the roll I8 is mounted in a yielding manner, the roll 18 will respond to different thicknesses of hide. As the hide is severed from the fiesh and fat by means of the knife 26, the flesh and fatare caused to pass to the mincing knives 39 which are secured to the shaft 40 and these knives 39 are adapted to cut the strips of flesh and fat into small particles.

It should also be understood that certain detail changes in the mechanical construction, arrangement and combination of parts may be employed without departing from the spirit of the invention, so long as such changes fall within the scope of the appended claims.
